Sabah Tea Plantation is the largest organic tea plantation in the state of Sabah. It is situated in the elevation of 1200m as the highest and produces one of the finest tea grade around the world. The optimal yield production is hindered by the presence of root disease, with the most common one being the red root disease. The causal agent of this red root disease is believed to be Poria hypolateritia of the class Basidiomycetes. In identifying the causal pathogen of the root disease, three samples of roots were taken from each of five infected root tea bushes at Sabah Tea. The fifteen root samples were placed in sterilized blue capped bottles and were brought back to Plant Technology laboratory of UMS for culture and identification using two different methods. The methods include root tissues culturing which is of obtaining pure cultures and root sample segmentation method as direct visualization of microbial infection. The presence of characteristics such as the spores, fruiting bodies, hyphae attachments, the presence or absence of hyphal septa and clamp connections. The microscopic examination resulted the confirmed group of pathogen where there is clamp connections does show that Poria hypolateritia is the causal pathogen. Future research can be carried out as pathogenicity tests conducted on Poria spp. thus leave room for control or prevention methods.
